The smaller scale homelab/selfhosting people really need a better solution. I think open source developers do as well.
What we really need is a small easy to set up solution that provides a clear way for us to integrate our app into it.
My ideal would be something that
* Supports ldap and OIDC
* Can be deployed to docker using one compose file
* Only needs to support hundreds of users (keep it simple, easy to deploy, and able to run on a raspberry pi)
* Provides basic user management, I want to be able to put users into groups and (if the app supports it) use those groups for in-app ACL.
If that service worked well in my homelab (a single-pc docker swarm that runs a few private web services like jellyfin) I'd very likely end up deploying it on my employers infrastructure. My employer is a small business with maybe ~30 users.
I'm not sure how to convert something like that into sales though. Still, starting with an open-source solution that solves problems for the little guys often has a "trickle up" effect.
Right now I'm looking towards https://github.com/sonicnkt/glauth-ui/ to solve that problem, but it's definitely not anywhere near there yet.
